[0044] A specific application of the present application is: the present utility model is suitable for supporting and subsequently lifting the counterweight of aerial vehicles during production. When in use, the initial position lifting plate 4 is located in the storage slot 2, and the counterweight is placed on the support plate 1 for temporary storage and support. When the counterweight needs to be transported from the support plate 1 by a forklift, etc., the electric push rod 10 is started, and the telescopic end of the electric push rod 10 is extended to drive the cam 8 to rotate through the cam hinge seat 9. One end of the cam 8 presses the pressing plate 11 downward, and the positioning rod 24 moves downward in the positioning cylinder 23 to horizontally position the pressing plate 11. The slider 13 is in the slide groove 12 slides, the guide rod 26 guides the slider 13, the swing rod 15 swings around the limit rod 17, and the other end of the swing rod 15 lifts the lifting plate 4 through the connecting rod 16 and the lifting frame 5. The lifting plate 4 lifts the counterweight upward and separates it from the support plate 1. The lifting plate 4 extends out of the storage slot 2, and the spring 22 is stretched. Then the forklift can insert the fork between the two groups of lifting plates 4 to lift the counterweight for transportation. Then the electric push rod 10 is reset, and the cam 8 rotates in the opposite direction. Due to the elastic force of the spring 22, the lifting plate 4 is pulled back into the storage slot 2 to keep the top surface of the support plate 1 flat.
